The AWS Knowledge Center helps answer the questions most frequently asked by AWS Support customers. The following 10 Knowledge Center security articles and videos have been the most viewed this month. It’s likely you’ve wondered about a few of these topics yourself, so here’s a chance to learn the answers!

  1. How do I create an AWS Identity and Access Management (IAM) policy to restrict access for an IAM user, group, or role to a particular Amazon Virtual Private Cloud (VPC)?
    Learn how to apply a custom IAM policy to restrict IAM user, group, or role permissions for creating and managing Amazon EC2 instances in a specified VPC.
  2. How do I use an MFA token to authenticate access to my AWS resources through the AWS CLI?
    One IAM best practice is to protect your account and its resources by using a multi-factor authentication (MFA) device. If you plan use the AWS Command Line Interface (CLI) while using an MFA device, you must create a temporary session token.
  3. Can I restrict an IAM user’s EC2 access to specific resources?
    This article demonstrates how to link multiple AWS accounts through AWS Organizations and isolate IAM user groups in their own accounts.
  4. I didn’t receive a validation email for the SSL certificate I requested through AWS Certificate Manager (ACM)—where is it?
    Can’t find your ACM validation emails? Be sure to check the email address to which you requested that ACM send validation emails.
  5. How do I create an IAM policy that has a source IP restriction but still allows users to switch roles in the AWS Management Console?
    Learn how to write an IAM policy that not only includes a source IP restriction but also lets your users switch roles in the console.
  6. How do I allow users from another account to access resources in my account through IAM?
    If you have the 12-digit account number and permissions to create and edit IAM roles and users for both accounts, you can permit specific IAM users to access resources in your account.
  7. What are the differences between a service control policy (SCP) and an IAM policy?
    Learn how to distinguish an SCP from an IAM policy.
  8. How do I share my customer master keys (CMKs) across multiple AWS accounts?
    To grant another account access to your CMKs, create an IAM policy on the secondary account that grants access to use your CMKs.
  9. How do I set up AWS Trusted Advisor notifications?
    Learn how to receive free weekly email notifications from Trusted Advisor.
  10. How do I use AWS Key Management Service (AWS KMS) encryption context to protect the integrity of encrypted data?
    Encryption context name-value pairs used with AWS KMS encryption and decryption operations provide a method for checking ciphertext authenticity. Learn how to use encryption context to help protect your encrypted data.

The AWS Security Blog will publish an updated version of this list regularly going forward. You also can subscribe to the AWS Knowledge Center Videos playlist on YouTube.

AWS Knowledge Center Video: Preparing to Send a Snowball Back to AWS

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/aws-knowledge-center-video-preparing-to-send-a-snowball-back-to-aws/

Do you know about the AWS Support Knowledge Center? It contains answers to some of the most frequently asked questions and other requests asked of our support team. Many of the answers even include a short video that serves to illustrate the process or to provide additional info on the topic.

For example, I recently stepped in to our studio and created a new video called Preparing to Send a Snowball Back to AWS. In 90 action-packed seconds, this video shows you how to power down the Snowball, stow the cables, lock the back panel, and verify that the proper return address is on the built-in display:

Visit the Knowledge Center to see other videos and to find answers to other questions that you might have about AWS.

AWS Big Data Blog Month in Review: March 2017

Post Syndicated from Derek Young original https://aws.amazon.com/blogs/big-data/aws-big-data-blog-month-in-review-march-2017/

Another month of big data solutions on the Big Data Blog. Please take a look at our summaries below and learn, comment, and share. Thank you for reading!

Analyze Security, Compliance, and Operational Activity Using AWS CloudTrail and Amazon Athena
In this blog post, walk through how to set up and use the recently released Amazon Athena CloudTrail SerDe to query CloudTrail log files for EC2 security group modifications, console sign-in activity, and operational account activity.  

Big Updates to the Big Data on AWS Training Course!
AWS offers a range of training resources to help you advance your knowledge with practical skills so you can get more out of the cloud. We’ve updated Big Data on AWS, a three-day, instructor-led training course to keep pace with the latest AWS big data innovations. This course allows you to hear big data best practices from an expert, get answers to your questions in person, and get hands-on practice using AWS big data services. 

Analyzing VPC Flow Logs with Amazon Kinesis Firehose, Amazon Athena, and Amazon QuickSight
In this blog post, build a serverless architecture using Amazon Kinesis Firehose, AWS Lambda, Amazon S3, Amazon Athena, and Amazon QuickSight to collect, store, query, and visualize flow logs. In building this solution, you also learn how to implement Athena best practices with regard to compressing and partitioning data so as to reduce query latencies and drive down query costs. 

Amazon Redshift Monitoring Now Supports End User Queries and Canaries
The serverless Amazon Redshift Monitoring utility lets you gather important performance metrics from your Redshift cluster’s system tables and persists the results in Amazon CloudWatch. You can now create your own diagnostic queries and plug-in “canaries” that monitor the runtime of your most vital end user queries. These user-defined metrics can be used to create dashboards and trigger Alarms and should improve visibility into workloads running on a Cluster.  

Running R on Amazon Athena
In this blog post, connect R/RStudio running on an Amazon EC2 instance with Athena. You’ll learn to build a simple interactive application with Athena and R. Athena can be used to store and query the underlying data for your big data applications using standard SQL, while R can be used to interactively query Athena and generate analytical insights using the powerful set of libraries that R provides. This post has been translated into Japanese. 

Top 10 Performance Tuning Tips for Amazon Athena
In this blog post, we review the top 10 tips that can improve query performance. We focus on aspects related to storing data in Amazon S3 and tuning specific to queries. Amazon Athena uses Presto to run SQL queries and hence some of the advice will work if you are running Presto on Amazon EMR. This post has been translated into Japanese. 

Big Data Resources on the AWS Knowledge Center
The AWS Knowledge Center answers the questions we receive most frequently from AWS customers. It is a resource for you that is distinct from AWS Documentation, the AWS Discussion Forums, and the AWS Support Center. It covers questions from across every AWS service. This post is an introduction to Big Data resources on the AWS Knowledge Center. 

Encrypt and Decrypt Amazon Kinesis Records Using AWS KMS
In this bog post, learn to build encryption and decryption into sample Kinesis producer and consumer applications using the Amazon Kinesis Producer Library (KPL), the Amazon Kinesis Consumer Library (KCL), AWS KMS, and the aws-encryption-sdk. The methods and the techniques used in this post to encrypt and decrypt Kinesis records can be easily replicated into your architecture.
